Hello all!
I have noticed that recently, my phone has been doing a very odd thing while charging. When it has been plugged in for a little while, and the screen is on and in use, sometimes the phone will crash. When it crashes in this manner, the backlight on the screen is turned on on full brightness, the screen gets a yellowish hue, and horizontal black bars start appearing on the screen. More black bars keep appearing until I reset the phone (hold the power button), and then there is no evidence of any screen problems. I also generally have to unplug it for a while, as if this happens once, it generally happens multiple times until I unplug the phone and wait. These problems seem to be occurring at odd times (a lot at night, before I am going to sleep), and have just started happening (I also recently made the upgrade from the latest version of GB to 4.0.4). I have had this device for about a year now (the second device, the first one had a physical design flaw and was replaced), and I am out of warranty right now, so any help would be appreciated!

That was happening to me (for a weird reason, my devicewas new, its seems that problem is more common in the rogers version dont know why) but, if your problem is the same problem that i had, then, just install stock ICS with oneclick (dont remember the name very well)

Superoneclick? That's the closest I found, and it doesn't say that it supports the Glide. And, I am running a fully stock version of 4.0.4, unrooted and everything. I might need a little more help here, haha.
I mean, oneclick, is the firmware,and is about 700 mb, give me amoment a will search it
EDit: i found it: http://www.androidauthority.com/captivate-glide-sgh-i927-att-android-4-0-4-ics-uclg9-leak-110365/
I use that, when I install it, that problem gone away, try it. And then, you can flash the custom recovery and install custom roms

Isn't that a different version though? The build number on that is UCLG9, not UCKJ3 (which is what I have right now).
I am not sure, but, if with that your problem persist, maybe is hardware, but I only do that. When I did it, that was the latest version, now there is another version but not sure what is it
I was having the same problem, except it was happening frequently after my phone had warmed up due to normal use. If the phone was already hot it wouldn't even get past the splash screen.
I put it down to hardware fault, and was successful in getting it replaced under warranty. The new one has been totally fine.
Hopefully yours isn't a hardware issue - but from how it sounds it very well could be

I really was hoping it was a OS issue, as it hadn't ever done this on GB. If I flash a new rom then, it would be fixed?
Also, I too noticed that my phone is abnormally warm when it does this. I do have a cover on my phone, but I noticed that it seems to be centered about on the horizontal center of the phone, about a half-inch below the camera. If this is related, what do you think it is?
My phone did this as well. Luckily it happened just before I rooted. The att guys said it was a hardware fault and that fault also killed my battery. I'm assuming it was a short. It started as something infrequent, but it eventually escalated to the point the second I turned it on my screen turned completely green and got really hot.

Just great, a possible hardware problem while out of warranty. Did yours do it only when charging as well?

Didn't have to be charging to do it. Could have been on the street holding it. (I was on GB as well)

Your issue sounds similar, but slightly different. Mine only happens while I am charging it, and it has only done it since a while after I made the upgrade to 4.0.4. Although, they sound similar, and my phone also gets concerningly warm, so I have no idea if it is the same thing or not...
If it's out of warranty, then you have nothing to lose by doing a backup and a clean ROM installation, which is what I would do. I guess if you do it when fully charged and while the phone is cold you should be fairly safe, especially if you use a small ROM. I've found the latest M3 10.1 ROM installs fairly quickly, so that might be worth a shot even just to see if it fixes the problem.
The only risk you're taking is that the phone might die and get bricked in the process if it's a hardware fault, so I guess it's really your call.
EDIT: On that thought, perhaps experiment with seeing if you can charge after leaving it in the fridge for about 15 minutes? It's a trick we used to use to recover data from failing hard drives, if you get them cold enough they can work for long enough to get away with things

I like that idea, as it should fix the overheating issue. However, the times that it actually has this malady aren't regular - it seems to happen more at night, but not every night. I could try putting it in the freezer when it does it though, and see if it works. If it is overheating, could it be a hardware issue then? I also noticed that my battery that I have in my phone does appear to have a slight dent near the bottom, and it is only happening when it is charging, so I am wondering if it could be a problem with the battery? When I pull the battery out after it has done this, the battery itself isn't that warm, but the phone is, so I'm thinking it isn't the battery, but does anyone else have any ideas?
Hello XDA members, this time I'm writing to all of you to tell you something that happened to my Optimus G E987 from Claro Argentina, also, to ask you something related to the topic.
I bought this phone about 4-5 months ago, and I have taken really good care of it, without using any film protection or case, it was working perfect and with not a single scratch on it, not even a little hit.
But then, some days ago, I decided to "protect it" a little bit, so I got one of this:
htt-p://i[dot]imgur[dot]com/YtgK1aS[dot]jpg
htt-p://i[dot]imgur.com/la1kI5e[dot]jpg
(Sorry, I'm new to this forum so it won't let me post links)
I used it like.. dunno, 3-4 days. One night, my phone was on 53% battery, to lazy to charge it so I just let it like that. Next day I gave it some use, so it dropped to 33% of battery life, I had to go work so I turned it off. When I finished, I tried to turn it on again, but nothing happened, tried more times and nothing, then I noticed I liiiitle light in the screen, the phone was turned on, but with REALLY low visibility, almost everything black but with a little of sight.
I though it was just a battery problem, so I charged it, but to my surprise, nothing happened, well something did happen, the little bit of sight that I had just went full black with no visibility. I noticed that the touch screen and buttons actually worked, I could "easily" navigate through the phone by just using it as normal, but without seeing (you can do this by just knowing your phone a bit).
And that's the story, basically, after using that case, the phone "casually" stopped working properly, all I got was a functionally phone with a black screen.
I managed to connect it to my pc through wifi and launched Android Screen Cast, to see what was happening on my phone. The glow was at 100% (I tried changing it) and everything seemed normal.
If you don't want to read, here is a TL;DR
>Bought Magnetic* Flip Stand Leather Wallet Case for Optimus G
>Some days after, phone screen stopped working (phone was still normally working, just with a full black screen)
About the Magnetic thing.. is there any possibility that this was the problem? the magnetic thing?
Btw, I sent the phone to tech service because it was still on warranty and they have me a new one, now I'm scared of putting it again in the leather case I bought, I don't want this to happen again.
Something to comment? hope you can give me some advice, thanks in advance!
Also having similar problems as you. Somehow, i am quite sure its the stock rom causing the problem.
Had the very same issue few weeks ago, had to send the phone back to LG ( who replaced the motherboard :/).
I was also on stock rom, had root and unlock bootloader (of course I clean all that **** before sending it back).
For my part, I was unable to go to recovery and download mode was quit impossible to access (may be my finger fault )
BUT! some time if I let the phone off for a moment or spam the power key, the backlight turn back on until I power down the phone, so it's could be a software issue ...
Anyway, an other info, when the backlight was off, if i tried to change backlight level i was getting a error message about overeating or something like that...
I dropped by tablet battery down once and now every so often the screen flickers with vertical lines and this is followed by loss of network and the thing reboots.
I've read this to be a battery problem.
Warranty is still active but I've rooted it and my Knox counter has gone up.
What do you think XDA? Just get a replacement battery?

If you have the ability, since it was dropped, I would open it and make sure connection is tight to battery and screen. Then if it still acts up, get a battery. Several people had battery issues out of the box. All it turned out to be for a few was a loose connection.
i was thinking about that but i'm afraid of voiding warranty. do i even still have warranty? due to the knox?

Well ive opened it up and tightened everything i can see and it seems to work ok for a while, when the charge gets to around 20-30%, the tablet flickers, all mobile connections are lost and 75% of the time, reboots.
So i went ahead and got a new battery. Now this was worse kinda. At random moments, like unlocking the screen, or replying to a message, or maybe just a high cpu load event, the tablet just turns off and is unable to be powered back on without first connecting it to a power supply like a wall charger or a power bank.
The time and date will be reset once its back on and ill have to wait a few minutes before the auto network time setting kicks in before i can use something like whatsapp.
Anyone got any clue what might be causing this problem? Thanks in advance, helpful xdarians.

I'm not by any means an expert or repairman of any kind, just so you know. I'm thinking maybe a loose connection at the terminals on the board the battery connects to or if they use a separate board for the battery to connect to and then to the main board it may be somewhere along in there. Maybe a loose wire going into the tab that connects to the prongs. It sure sounds like something isn't making a good connection. Sounds like a load gets put on it and it and that bad connection can't handle the load.
Might just be you're going to have to send it off...
You may be right. Sounds like a particular connection which does higher load or something. Once i put the tablet in power save mode, the symptoms never reappeared. I dont notice a drastic slowdown in the tablet either. Probably am prolonging the inevitable.

I am facing exactly same issue what you have described and am in same situation, have tripped Knox on my Tab S 8.4.
I can see that you have been able to suppress the behavior by putting it to Power Saving mode. Have you experienced flicker and reboot since then? I am planning to take it to Samsung store not sure if they will honor warranty, did you tried that?

nope, ever since the Power Saving mode solution, it hasnt flickered and rebooted yet. and my warranty was expired by that point so i didnt bring it to the shop. no noticable reduction in performance so far
possible battery connector

I have seen this problems on 2 tablets 10.5 and 8.4 the connector where battery is connected on motherboard gets loose which causes reboots and flicker
Solution in my case was resoldering that connector again
i had the same problem, opened up my tablet, just disconnected the battery, cleaned the contacts, pushed it back, made sure its nice and snug, put it all back together and now battery doesn't drain as fast, no more flickers and reboots!
hmm. i'll have to give it a try. you think this may be something to do with condensation?
Sorry for the bump, but I'm having this issue as well on my S 8.4. Custom ROM. The thing with me is that it's not consistent. One day, it will do it a few times; others, no issues whatsoever. I'll try the suggested if it gets progressively worse.
Hey guys,
Unfortunately our home's tablet (Tab s 8.4 Wifi) has the same problem.
It never did weird whatshowever, but when I flashed a custom rom (which went perfectly smooth actually) the screen flashes and the tablet reboots sometimes.
Now it weird that this never happened before and only when I flashed a custom rom it began showing this behaviour.
I am affraid of opening this tablet, and I guess because of the custom rom there is no warranty left anymore (or can this be bypassed by some terminal trick?)
Also I question myself if this is not a software issue, and that it can be fixed with software or so?
Thanks for answering!
My Fix
Hey Guys!
I might have some surprising news to tell about this "issue".
I saw some unboxing video's and saw at what place the battery connector was placed. It was some sort of a 'push to click' system.
So what I did was the following:
I pushed the tablet at the place of the battery connector. I tried this at various places until I heard a *click*.
Now I don't have this issue anymore. Jay!
I hope this will help you too!
I started to have the same issue on a Tab Pro 12.2, presumably after the battery has lost considerable amount of its energy. Normally I remember this tablet to have a dazzling 10+ hours of usage time. Just after some serious usage time of more than 2 years this issue started, along with increasing temperature and finally reboot. From time to time Android gave a warning message about overheating. From time to time charge values drop big values at a time. From 45 to 20 or 80 to 50. Seems arbitrary. This was happening even when I was on stock, then I switched to some Android 6 stock port from some other tablet. Still the same.
I believe the battery needs replacement. (That's obvious after 18 months, I just mean blinking is related to this) Hope I can find a high quality one cause there are several garbage batteries.
This problem just started about a week ago. Sometimes after a few seconds of the screen being on, it will flicker, mostly at the corners. However, most of the time it will distort and eventually fade to black. It mostly seems to do it when the phone is warmer. For instance, in my office at work or home, where it's cool, it will not happen hardly at all. But in my truck on the way home, outside, or if I can feel heat on the back of the phone, it does it a lot.
All of that said, I know of the paper/eraser trick on the camera connector (which is very temporary, from what I've researched), but to me this seems to be a GPU/heat problem. Basically, I'm just trying to understand why this might be occurring. I don't want to order a new mobo and have it do the same thing. So, any help would be much appreciated!
How often is this happening to people??

I had a similar problem for about two months. I tried the paper thing over the camera sensor and I felt like it helped some but the problem still continued. The screen would just slowly go dark with vertical lines running through it. All apps would still work in the background while this was happening. I could boot to TWRP and this problem never happened while in TWRP which was odd. Seemed like if it was a screen issues or hardware malfunction it would happen all the time. That's when I decided to just flash back to stock. I was thinking about getting the S8 anyways so what the hell. I flashed to stock 10B and took every single OTA. Took all night but I've been running stock for over a day now and the issue has not replicated itself one time since reverting back to stock. I was on RR Nougat and Fulmics when it happened prior. Has to be a root or Rom issue? What ROM are you on?

I became so fed up with the issue that I caved and bought the Nexus 6P last year. My G3 was on stock OS, no ROMs. Pretty sure it was a hardware issue. I turn it on every now and again, and the same thing happens. Never really solved it. I may try flashing some ROMs at some point, but I think I'm done with Samsung devices for the time being. I absolutely love my Nexus 6P. Great phone. Waiting for the new version of the Pixel or the rumored new Nexus haha.
It's an issue due to bad quality soldering and the SoC overheating. When the phone is very warm (and the G3 tends to get quite warm on the Camera) and you keep using it, the bad soldering starts losing con ection.
So you're basically losing connection to your chip and that's why the phone is experiencing those problems. That's why putting pressure on the chip helps to restore the connection.
It's best to use a thermal pad and it's the best solution there is. Some people bake their motherboards but I don't recommend it since this always kills the motherboard in a few months.
You can also try looking for a replacement motherboard online.

Mine screen fades to brightnes, and strips when phone is cold. when it gets worm hot screen is almost perfect. same thing with two mobo's.
I'm back again XDA. Even more G3 problems!
So since the last time I posted, I've replaced the board on my G3. Everything was great up until the SIM reader quit out. Switched to an HTC One M9 and boy is it terrible. So I use the G3 for music, games, etc. Didn't bother rooting or anything. Running VS9854BA. It's always on Airplane mode with WiFi enabled, I try not to let it overheat since the WiFi went to **** on my last board. And what do ya know, as I was typing up a comment on Facebook the thing just freezes up, makes some ****ed up screeching noise, and tries to restart. I get boot looped and notice a red and blue led. So I pull the battery, hold down the power for a bit and throw the battery back in. It boots up. A few minutes later the phone freezes and does the same thing. The battery level was around 80% on this battery. I try another OEM battery and it works fine for the rest of the night. However, the phone is now doing the same thing with that battery. I've only had issues with non official batteries in the past. For example, one battery I have will make the phone reboot after using the camera. Anyways, I'm iffy on purchasing a new battery. I don't want to pay $6-10 on a POS that was made in 2014. And I don't want to gamble on buying a $15-20 OEM battery from LG, as it may still be old and degraded; or won't even solve the problem. I tried contacting LG to see if I could get any insight, or to see if they are selling newer manufactured BL-53YH batteries and have yet to hear from them. I have noticed most people have issues with LG phones two months after their warranty ends. I was surprised to see the G3 last a few years and would like to get some more time out of it. If my 2011 galaxy nexus still works flawlessly, so should the G3. In the meantime I put a little noctua thermal paste on the EMMC and was baffled by the temperature decrease in cpu z. It still doesn't fix anything though. Any thoughts here? Should I gamble and buy the battery or is this hardware failure?
TLDR: LG devices may be time bombs and their support sucks.
There seems to be a lot of bootloop/battery issues this week. I hope device is not a "time bomb".

"...as I was typing up a comment on Facebook..."
Maybe it's just the universe trying to tell you that Facebook sucks?
Kidding aside - it sounds like your phone is dying a slow death. Normally if you had just the restart issue I would suggest a new battery(even with the reboot at 80% - old batteries get weird), but with the sim issue combined with the screeching noise red/blue light reboot - which usually delivers a green screen kernel panic reboot - it sounds like the weirdness that occurs when a G3 dies.
If it were a bad battery I think it would just shut down, reboot to the LG logo, and then bootloop(that's what mine did when it failed); but failing G3 batteries do some weird things sometimes. To t-shoot a bad battery I guess you could try plugging the phone in and using it while charging to see if any troubles occur; if not, then invest in a battery. I can't say that is a fool proof way to check the battery though...the best way is always to replace it.
If it's (what is believed to be) a solder issue on the board - which a lot of G3 users have reported as the phone has aged - you can try the paper trick to create enough pressure on the chips to complete the solder connection or even using some heat to try and get some solder to reflow, but those are generally only temporary fixes...the issue usually comes back in time. It may be worth it to try the paper trick to help you troubleshoot your issues - if the trick fixes it briefly then you know it's a hardware issue and you can make a decision from there. If you have one of these solder issues it's just best to move on.
So flip a coin: replace the battery for @$20, or say eff-it and get a new phone; sounds like a tough decision...glad I'm not making it - yet.
*If you don't know what the paper trick is just search the G3 forums...screen flicker threads usually mention it and there are other threads out there too.
